From ab5e67d7513ac6efb4c0ee9787aeaa41604c0566 Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Sat, 14 Jul 2018 18:38:59 +0000 Subject: [PATCH 1/1] sequencer: pass absolute GIT_WORK_TREE to exec commands The sequencer currently passes GIT_DIR, but not GIT_WORK_TREE, to exec commands. In that configuration, we assume that whatever directory we're in is the top level of the work tree, and git rev-parse --show-toplevel responds accordingly. However, when we're in a subdirectory, that isn't correct: we respond with the subdirectory as the top level, resulting in unexpected behavior. Ensure that we pass GIT_WORK_TREE as well as GIT_DIR so that git operations within subdirectories work correctly. Note that we are guaranteed to have a work tree in this case: the relevant sequencer functions are called only from revert, cherry-pick, and rebase--helper; all of these commands require a working tree.
